F all 107mm it may concern:

Be it known that l, PHILIP E.y MONROE, citizen of the United States, zresiding at llfeymouth, county of Norfolk, `,State of Massachusetts, have invented afcertain new and useful Improvement in later-Closets for Yachts and other Small Boats, of which the following is a specification, reference being had therein to the accompanying drawings.

ln small yachts and other boats inwhich the head room is low and the watercloset must be located below the water-line,.diflicult-y has heretofore been experienced in the construction of water closets that are convenient, yon account of the low head room. The closet is usually mountedin the counter of the boat below the water line. As heretofore constructed there has `usually been employed a pump or some other suction 'device for discharging the contents of the bowl into `the water.

The. object of the present invention is toV provide a device which can be installed be` low the waterlinegand which shall be more especially adapted` for use in yachts and other boats where there is low head room.

The closet embodying in'y invention is" applicable to various uses and if desired may be placed'above the water line, although primarily intendedfor use below.

The invention willbe fully understood from the following description taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined `in the claims at the close of the specificationl In the drawings,-Figure'1 is ar vertical section of a device embodying the invention and showing the seat and cover closed. Fig.

2 is a plan of the device closed, as in Fig. 1. Fig. 3 is a vertical section on the same line as Fig. 1k but showing the valve opened for discharging the contents. Fig. l is a vertical section-'on a largerscale and partly Vbroken away to show the manner ofl locking together the operating plunger 'with the stem of the lower valve. f Fig. 5 is a vertical section partly broken away taken at right angles to Fig. fl. Fig. 6 is a horizontal sec#rvr tion of the device in the position occupied by the parts before the operating plunger is turned to lock together the piston and the stem of the valve Fig. 7 is a section on the same line as Figli, showing the parts as they appear after the operating plungeris turned to lock the parts together, as shown in Fig. 4. Fig. 8 is a detailed view Lshowing the handle of the operatingk plunger locked in its closed horizontal position sectioned on line 8-8 of Fig. 1. Fig. r9fis a horizontal section on line 9 9 of Fig. 1. Referring now to the drawings, 1 represcnts the bowl which is provided with an annular seat 2. The bowl has an opening at the bottom with which is connected a discharge pipe 3 which passes down through the counter` of the boat, (not shown) its lower end opening under the water, all the parts being below the water line. The bowl is made very Hat and shallow and may `be provided with a curved and slanting guide el, leading from the upper edge of the bowl at the inner periphery of the seat kdown to' the rim of the upper end of the discharge pipe 3 for the purpose of deiiecting or direc-ting the matter into the discharge pipe. The seat is provided with a cover er support 5 connected kby hinges 6, 6 with the ledge 7 on the upper side of the seat 2'.

The part 5 is shown in the form of a cover for the seat, but it performs thegmore important function of supporting certain of the partsby which the device is operated. I have, therefore, referred to it as a "supf port. The lower end of the discharge pipe Suis normally closed by a valve 8 as foil lows: Secured in the lower part of the pipe 8' is a cross piece 9 which extends diametrically crosswise of the interior of the pipe, the yend portions ofthis cross piece being web-shaped with the broad faces in a yvertical position and having in the middle a tubular hub-shaped portion 10. The valve 8 is, provided with a tubular stem 11 which extends up through the hub 10 ofthe cross f piece 9 and has a sliding fit therein ,-andfis provided on its lower end with ahoriaontal Hangs 12.y On the lower side'of the valve8,

isa dislf13 and the valve 8 is clamped "between the flange 12' and the disk 13 by bolts thereof and a pin 17 eXtends horizontally through said slot 16 and is secured at its ends to the opposite sides of the discharge pipe 3. A coil spring 18 is mounted within said tubular stem 11, its lower Yend resting upon saidy pin 17 and itsupper end bearing against theinside of the upper end of the stern 11 so that when the stem 11 is pushed down and thereby the valve .8 Yispushed down out of the lower end of the discharge pipeV the spring 18 willbe compressed, but

when the-downward pressure is released, the

spring 18 will pull the valve back to its uppermost position against the valve seat 15.y rlhe pressure of the water on the lower side ofthe valve 8 together with the spring 18 holdsthe said valve forcibly against the valve seat and'secures a Aperfect closure at all times. On the uppery end of the tubular stem 11 is an upwardly extending shank 19 terminating in a flange or button 2O ywhich isf preferably formed with upwardlytapering sides. The said button forms a' part of the interlocking connection with the piston, as iwillfbe hereinafter described.r

l/Vhilel have described the valve 8 as in l the form. of a piston operated in part by a spring, I' do not limit myself to this construction because believe that under most jcondition's 'other types of valvesv will operf ate equally well since the water'pressure on @fue the 'valve is considerable.'V

I The piston is forconvenience of construc- 1 tion and assembling, preferably composed of two disks 21,22V whichy are map-de of rubberor other suitable material and are secured to a hollow stern 23 by means of bolts 24 which. passk through awasher 25 on the lower yside of the disk 22 and pass up through the disks 21 into the flange 2G of the stein` 122 and l The disk 21 is formedwith a recess 27 in` itsunder side which is adapted to receive the headr20 of thel button on the upper end of 'l thevalve stem 11'when the Vpiston is pushed down, as ,will be hereinafter described.` A short rod 28 hasy a sliding fity inside of the tubular steml 23 whichfis provided with a horizontal slot 29l which is engaged by a4V pin 30V projecting from Vthe side of the rod V.28,1thus 'providing for a slight swiveling movement of the rod 28 within the tubular Y stem 423, but at the same time preventing any Vaus Vnally on saidfrod .and is somewhat-,shorter thanwtherod 732..vk A spring 3,5 `isi-,coiled around thesaid rod 32 Ynear the upper end,

Y oneV end yof saidspring bearing against the upper end ,of the sleeve 34 and the other end of said spring bearing against a shoulder 36 on the 'lower vend of the shank of the handlev 33. This spring is under tension and kwhen the said'rod 32 is turned into a vertical position, asshown in Fig. 3, thesaid spring Ypresses the sleeve 34 down so that itsV lower end bears against the upper lend of the tubular stem 23 of the piston, thus holding rigidly together rthe rod'32 and the rod 28 so that they will not bend at the joint formed vbythe hinge, but when it is desired to place the lever' in the horizontal position when the rod and lpiston areat the upper end of their stroke, the rod may be bent at Vits joint, asl shown in Fig. 1, the spring'35 being put un-4V der tension. 1

'Thecover or support 5V is formed lwith a hole in which is mounted acircular boX'or case 37 'having a downwardly extending annular flange on its under side into which fits the valve disk 21 and the case is formed with an upwardly extending tubular: boss 38 through which the stem 23 has 'a sliding fit,- so that when the piston is drawn *into its uppermost position, as. shown in Fig. 1, the piston will be within the case with the stein A23 extending up through the boss 38 Afar enough to bring the joint 31 between the two rods- 28 and 32 above theboss 38,' so" that the rod may be b ent at thejoint into kthe position show-n in Fig. 1.

. A catch is provided whereby the cover or `'support may be latched down to the seat 2.1 The means shown are as follows: A spring.

catch` 39is formed with a bent portion which Vis secured to thevupp'er side of the cover oi' support jand isfor'medwith arhook '40, c which projects down into a recess 41 in the seat 2 and engages with a catch in said recess. rIphe v'catch is formed with a cam faced bottom and has'suilicient elasticity so icc that vwhen the support 5'is pushed down the hook 40 will snap into engagement withthe catch 42. Secured tothe spring catch 39 is an upwardly extending member 43 bifurcated at itsupper'end, forming the fingers Y V44, 44 which areipreferably slightly yielding and are adapted vto receive between them the sleeve-34 which surrounds the rod 32 to Vpinch it with. sufcient firmness. Then it is desired to turn up the covery or support 5 on itsv hinge, the hook 40 should be disengaged from the catch (42. VThen by liftingv on the handle the cover will be raised and U turned back on its hinges with the handle. Y If itis desired simply to turn up the rod '32intog operative "vertical position 'without opening the coverthen the Vhandle 43 will be pulled up without first disengagingthe catch. 1

The annular/disk V22 which forms a part of the upper piston is formed with arecess in Vwhich is a flanged guide having upper and lower flanges 46 between which are held Y two coperatinglocking plates 47, 48 ywhich iin Y are respectively formed with the arc-shaped edges 49, 50, these arc-shaped edges being concentric with .the shank 19 of the button 2O and with the rod 28 when the rod 28 is in its normal position.v Projecting from the lower end of therod 28'are two pins 51 and 52 which engage respectively with holes or slots inthe plates 47, 48 so that by turning the rod 28 the two locking plates 47 and 48 may be moved in opposite directions in their guides, thus bringing the curved edges of the locking plates 47, 48 in toward the shank 19 and under the iiange of the button20, as shown in Figs. 4 and 7. This may be done by partially rotating the'rod 32 whenthe rod 32 is brought into 'the vertical position and pushed down, as shown in Fig. 3,'and as permitted by the horizontal slot 29. When this connection is made, by further pushingV down the rody 32 the valve stem 11 and the valve 8 will be pushed down together.

lf' the parts are in the position shown in F ig. 1 and F ig. 2 with the cover closed and the handle locked, then when it is desired merely' to open the cover for user of the s closet, the cover will be turned back on its hinges in the manner already described by lirst releasing the hook 39 from the catch 42 and thenvlifting on the handle 33 to turn back the cover.

ln practice, however, the plunger will ordinarily lift into engagement `with, the top of the lpipe 3, the valve 8 being closed, so that thereby there is'no possibility'of water in the pipe 8 slopping outL of the bowl when the boat is in rough sea. In such case, when it is desired to use the` closet the plunger should be lifted and then turned to enga-ge the sleeve 34 with the fork44 and then the cover should be thrownback as already described. After use the cover shouldy be closed and the cover and plunger f locked down.` Then,`the rod 32 yand. sleeve 34 will b'e turned up releasing the sleeve from the fork 44 and without releasing the latch 39 from the catch 42 and without opening the cover, `and the rod 32 and sleeve 34 are brought intok vertical position. The spring 35 will push the sleeve 34 down overk the hinge 31 into engagement withthe upper end of the tubular stem 23, and the two yends 32 and 28 will be held rigidly together. lThe' pushed downward,

handle 33 will 'then bek y causing the sleeve 34 and rod 32 together with the rod 28 and the piston 21 and parts connected therewith to descend' until the annular'washer 25 onythe under side of the disk 22 strikes on the shoulder at the upper end of the tubular stem 11 in the manner shown in Fig. 4 while the valve 8 is still in its highest position, as shown in Fig. 1. At this stage the locking plates 47 and 48 will not be engaged with the button 20.l The operator can readily tell by sense offeeling u when the upper pistonfstrikes against the f,

into the pipe will be pushed down by the upper piston and it will pass out through they lower end of the discharge pipe. The water will rush into the now open end of the pipe and will thoroughly wash out the portion of the pipe which is below the disks 21,

22 which form the upper piston. The said i piston vhas a water-tight tit inthe discharge pipe,so that the waterkcannot rise above it. The plunger rod will then'be raised by pulling up on the handle 33, thus lifting the piston disks 21, 22 and valve 8y until both arc returned to their normal position, the valve 8 again closingthe lower end of the discharge pipe. The space in the discharge pipe between'the valve 8 and the piston disk 22 will remainlled with water which will have rushed in, but it cannot rise above the piston 22. lt is desirable to have this chamber between the valve 8 and the piston 22 remain filled with water as it keeps the pipe more thoroughly cleansed. In the raising ofthe plunger rod, as soon as the valve 8 has reached itsvuppermost position seated against the valve seat 15 the rod 32 should be rotated 1n a backward direction to release the locking plates 47, 48 from engageto'leave the plunger piston in engagement with the upper end of the pipe 3 to prevent splashing of water out of the bowl as already mentioned.y Y

lVhen the plunger andvalve are pushed down, as already described, 4to discharge the contents of the bowl, the spring 18 will be 'compressed as shown in Fig. 3, 4and when the downward pressure is released the expansion of the spring 18 will tend to lift the'valve 8 as well as the piston and rod even without any force exerted by the operator. This is intended as a safety attachment so that if by any-chance the operator should carelessly turn the rod 32 to unlock thefplates 47, `4,8 while the piston 8 is still in its lowermost position instead of waiting until it has become seated the spring 18-will lii;

serve to immediately raise the valve. Otheriso moved out of the discharge pipe 3 the water would rush in, overflow the bowl and flood vthe compartment.

In ordinary use ofthe device, it is desir'- able to give the piston a second or third complete vertical stroke as therebythe parts Vwill be more ythoroughly cleansed and rinsed, and danger of fouling will be lessf ened. n

In a water closet for use on small yachts and other boats, a bowl, a discharge stem of the lowerY said upper piston f pipe connected with the bottom of the bowl and open at its lower end, a piston anda valve, one above the other, which have ar sliding iit in said discharge pipe, means for actuating said piston and valve whereby the piston may be moved Vdown into the dischargepipe and up out of the discharge pipe, and whereby the valve may be moved down out of the lower end of the discharge pipe and back into the Vdischarge pipe, and means controllinglthe relative positions of said piston and valve so that wheneverk either the piston or the valve is out of the discharge pipe the other Aof said two mem bers will be within the discharge pipe.

20. ii a water closet .for use on small yachts and `other-boats, a bowl, a discharge pipe connected with the bottom of the bowl and openat its lower end, a piston and a valve, one above the other, which have a sliding `tit in said discharge pipe, means for actuating said piston and valve whereby the piston may be moved down into the discharge pipe and up out of the discharge iipe and whereby the said valve may be moved down out of the lower end of the discharge pipe and back into the discharge pipe, means controlling the relative positions of said piston and valve so that whenever either said piston or said valve is out of the discharge pipe and the other of said two members will be within the discharge pipe, a separable connection between said piston and valve controlled by the operator the valve isr outof the discharge p ipe the other will be within the discharge pipe.

22. In a waterV closet .for use on boats, a bowl, a discharge pipe'connected with the bowl, a valve .controlling the dischargeV opening of the saidpipe, and a piston normally outof engagement with the said pipe Y and withsaid valve and having a range of movement while said valve isjstationary but adapted and arranged to descend `intoythe pipe closing it and opening said valve and forcing the contents of the pipe past the said valve. v Y
